Y91 stereo question

[jsbihn]

Yeah, I didnt think that the 03's came with it... especially since I have and OnStar module.
Given, I wouldnt care to retro fit.
Just wondering if say a 2005-2009 radio could retro into our trucks without mods.?
Also, what would I expect to pay roughly if I found a Nav unit?
I mean I know our 6 disc Y91 units can go from 50-75 bucks roughly..... so what do you think a decent Nav unit go for?

It would physically fit without problem, but you would still have to find the global positioning module.

But would it work with the module in a later truck?

That I can't say, seeing a how a dealer has to program it to unlock it, a good bet would be to ask them, although it depends who you speak to, have to find someone with experience over someone that just reads out what their computers tell them.
